Description

Technical Field

[0001] This utility model relates to the field of filtration structure technology, specifically to an ammonia nitrogen detection and sampling filtration structure suitable for wastewater with high suspended solids. Background Technology

[0002] In the detection of ammonia nitrogen in wastewater with high suspended solids, sampling and filtration are crucial steps to ensure accuracy. However, existing filtration structures often suffer from the following problems: First, the disassembly and assembly of the filter cover and the main body of the device are cumbersome and require tools, leading to inefficiency when cleaning or replacing the filter cover and affecting the detection progress. Second, during filtration, the filter cover is prone to clogging due to the adhesion of suspended solids, and the lack of an effective vibration-assisted structure results in a significant decrease in filtration efficiency over time, making it difficult to stably adapt to the filtration needs of wastewater with high suspended solids, thus affecting the accuracy of ammonia nitrogen detection.

[0003] To address this issue, we propose a sampling and filtration structure for ammonia nitrogen detection in wastewater with high suspended solids. Utility Model Content

[0006] Preferably, the top surface of the first annular plate is fixedly equipped with two U-shaped handles, which facilitate the disassembly and assembly of the filter cover.

[0007] Preferably, the assembly / disassembly assembly includes a mounting column and a hollow column. The top end of the mounting column is fixedly installed to the bottom surface of the first annular plate, and the outer wall of the hollow column is fixedly installed to a columnar opening on the top surface of the second annular plate.

[0016] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0017] like Figure 1-5 As shown, this utility model provides a technical solution: an ammonia nitrogen detection sampling and filtration structure suitable for wastewater with high suspended solids, including an outer cover 1, which is arranged longitudinally. A first annular plate 2 is slidably arranged on the inner wall of the outer cover 1, and a filter cover 3 is fixedly installed on the inner wall of the first annular plate 2. Two U-shaped handles 4 are fixedly installed in pairs on the top surface of the first annular plate 2, which facilitate the disassembly and assembly of the filter cover 3. A second annular plate 5 is arranged below the first annular plate 2. The second annular plate 5 is installed and assembled with the filter cover 3 through a disassembly and assembly assembly, which includes a mounting column 6 and a hollow column 8. The top of the mounting column 6 is fixedly installed with the bottom surface of the first annular plate 2, and the outer wall of the hollow column 8 is fixedly installed with a cylindrical opening on the top surface of the second annular plate 5. The mounting column 6 and the hollow column 8 are through-through. A limiting column 10 is fixedly installed on the outer wall of the mounting column 6, and the outer wall of the limiting column 10 is fixed with the inner wall of the hollow column 8. The wall sliding setting, with the setting of the limiting column 10, can prevent the filter cover 3 from shaking. The top surface of the hollow column 8 is fixedly installed with an upper horn sleeve 9, and the bottom end of the hollow column 8 is fixedly installed with a lower horn sleeve 11 that is the same size and shape as the upper horn sleeve 9. The inner surface of the lower horn sleeve 11 is in contact with the arc-shaped abutment 13. The curved surfaces of the inner surfaces of the upper horn sleeve 9 and the lower horn sleeve 11 can be used to facilitate the installation and removal of the arc-shaped abutment 13. An elastic body 12 is fixedly installed on the outer wall of the lower end of the mounting column 6. The elastic body 12 is made of rubber. The end of the elastic body 12 is fixedly installed with the arc-shaped abutment 13. A spring 7 is sleeved on the outside of the mounting column 6. One end of the spring 7 is fixedly installed with the bottom surface of the first annular plate 2, and the bottom end of the spring 7 is pressed against the top surface of the second annular plate 5. The setting of the spring 7 can realize the up and down vibration of the filter cover 3 during the process of filtering sewage through the filter cover 3, so as to improve its filtration effect.

[0018] This ammonia nitrogen detection and sampling filtration structure, suitable for wastewater with high suspended solids, allows wastewater to enter the outer casing 1 and be filtered by the filter cover 3 for high suspended solids. The assembly and disassembly components enable quick assembly and disassembly of the filter cover 3 and the second annular plate 5. During installation, the mounting column 6 penetrates the hollow column 8. The rubber elastic body 12, when compressed, causes the arc-shaped abutment 13 to contract. After passing through the hollow column 8, the elastic body 12 returns to its original position, causing the arc-shaped abutment 13 to abut against the inner surface of the lower horn sleeve 11 and be fixed. The limiting column 10 slides along the inner wall of the hollow column 8, acting as a guide and limiter. During disassembly, pulling the handle 4 upwards causes the mounting column 6 to move the arc-shaped abutment 13 upwards. The arc-shaped abutment 13 contacts the upper horn sleeve 9 and contracts under compression, allowing the mounting column 6 to be pulled out of the hollow column 8 for easy cleaning or replacement of the filter cover 3, ensuring stable filtration performance. Here, the spring 7 allows the filter cover 3 to vibrate up and down during filtration, further enhancing its filtration effect.
